" But the approach to truth is not easy. There is only one way towards it, the way through error. Only through our errors can we learn; and only he will learn who is ready to appreciate and even to cherish the errors of others as stepping stones towards truth, and who searches for his own errors: who tries to find them, since only when he has become aware of them can he free himself from them.
